The correct answer is: B.The production of cAMP stops, and the pathway shuts down.

Explanation:

When the ligand is no longer attached to the receptor, the signal transduction pathway typically shuts down or is terminated. As a result, the production of second messengers like cAMP (cyclic adenosine monophosphate) stops, and the signaling pathway is deactivated. This prevents further amplification of the signal and allows the cell to reset.
